PLOW-POINT.

SPECIFICATION forming part of Letters Patent No. 364,912, dated June 14,1887.

Application filed April 5, 1887.

To all whomit may concern.-

Be it known that I, MICHAEL HARVEY EF- FINGER, a citizen of the UnitedStates, residing at Harrisonburg, in the county of Itocl'cingham andState of Virginia, have invented a new and useful Improvement inPlow-Points, of which the following is a specification.

My invention relates to improvements in plow-points; and it consists ina certain novel construction and arrangement of parts for service, fullydescribed hereinafter, specifically pointed out in the claim, andillustrated in the accompanying drawings. 1

Heretofore plow shares or points have been made with the nose portionprovided with jaws to receive a tongue on the slipnose; but

for various reasons these have been obj ectionable. The said jaws arevery liable, when the nose strikes'a stone or other unyieldingsubstance, to split apart, thus ruiningthe entire share, which must bereplaced at considerable expense.

My invention consists in forming the tongue or wedge on the extremity ofthe nose portion of the share, and providing the rear end of theslip-nose with jaws to embrace the same.

My invention consists, further, in certain details of construction andarrangement, as

. hereinafter more fullyset forth.

In the drawings, Figure 1 is a side view of the share. Fig. 2 is asimilar view of the opposite side thereof. Fig. 3 is a sectional view onthe line a: m, Fig. 1. Fig. 4 is a perspee tive view thereof, with theparts detached, to show the manner of placing the same together.

Referring to the drawings, in'which similar letters denote correspondingparts in all the figures, A designates the plow-point, having thewedge-shaped tongue B on the nose portion thereof, the said tongue beingformed in tegrally with the said nose portion, and having the lateralweb 0 extending along one side of the tongue, and the projection Dextending forwardly over the same.

G is theslip-nose, having the diverging jaws.

H H, provided on the inner sides with the grooves I I, to receive theribs K on the upper and lower sides of the tongue.

Serial No. 233,773. (No model.)

L is a pin, topass through aligned openings or recesses h 70 in theinner edge of one of the jaws H and one of the ribs K, respectively.

It will be seen that the web 0 on the side of the tongue, and formedintegrally with the same and alsowith the projection D, serves as apowerful brace to the said tongue to prevent its being broken when theshare is strained. The said web also serves as a lateral brace to theslip-nose, and, used in connection with the ribs and grooves, the saidslip'nose is very firmly braced laterally. The projection D over thetongue serves as a brace vertically to the slip-nose, to protect thesame in some measure nary strain; and should any portion of the dey vicewhatever split or be otherwise damaged it would necessarily be theslip-nose, the expense of replacing which is much less than the entireshare.

Having described my invention, I claim-- A plowshare having theforwardly'extending tapered tongue B, the upper and lower sides of whichdiverge rearwardly, ribs K on the said diverging sides, theforwardly-projecting projection or brace D, overhanging the said tongue,and the lateral strengthening-web 0, formed integrally with the saidtongue and upper projection, and adapted to firmly brace the same, incombination with the reversible slip-nose or point G, having thedivergingjaws H, grooves I in their opposing inner sides, adapted toreceivethe ribs K, and the pin L, passed transversely throughregistering-open ings in one of the jaws Hand one ofthe ribs K,substantially as and for the purpose set forth. I

In. testimony that I claim the foregoing as my own I have hereto affixedmy signature in presence of two witnesses.

MICHAEL HARVEY EFFINGER.
